Description
Technical field
A kind of intake tunnel layout pattern of Hydraulic and Hydro-Power Engineering is the utility model is related to, suitable for water inlet influent stream
Direction and diversion tunnel axis direction thereafter are inconsistent, after water inlet can layout area it is narrow and small, without abundance space arrangement gradually
Become the intake tunnel arrangement of section and plane curved segment.
Background technology
Intake tunnel water inlet centerline direction is generally inconsistent with the diversion tunnel axis direction after water inlet, is
Ensure the positive water inlet of powerhouse of hydropower station, beneficial to influent stream, intake tunnel needs plane of arrangement curved segment；Intake tunnel is intake
Mouth elevation and the installation elevation of hydraulic turbine of power station main building 9 are also inconsistent, and intake tunnel also needs to set vertical curved segment.Cause
This, as shown in Figure 1 and Figure 2, conventional power generation usage diversion tunnel arrangement is by water inlet section 1, transition 2, straightway 6, plane curved segment 7, perpendicular
Formed to the grade of curved segment 8.Transition immediately water inlet section, Transition length is generally 1~2D, and (D is that tunnel footpath or hole are wide）.Directly
The arrangement of line segment, plane curved segment and vertical curved segment should meet《Hydraulic tunnel design specification》(SL279-2016) relevant regulations：
1. hole line sets curved segment in the plane, the bending radius of low flow velocity pressurized tunnel is not preferably less than 3 Bei Dong footpaths or hole
Width, corner are not preferably greater than 60 °.
2. should set straightway in the head and the tail of planar curve path, length is not preferably less than 5 Bei Dong footpaths or hole is wide.
3. barrel section sets vertical curve, to high flow rate tunnel, its pattern and vertical curve radius should be true by testing
Fixed, preferably less than 5 times of hole footpath or hole are wide for the vertical curve radius of low flow velocity non-pressure tunnel, and low flow velocity pressurized tunnel can suitably drop
Low requirement.
According to above relevant regulations and requirement, water inlet need to such as arrange transition, straightway, plane curved segment, it is necessary to have
Appropriate layout area, that is, entering hole point A to the distance S of water inlet axis and the intersection points B of diversion tunnel axis should meet：S≥6D+
3Dtanθ/2。
When being limited by topographic and geologic condition, water inlet and factory building relative position, such as water inlet Duan Houke layout areas
It is very narrow and small, there is no space arrangement transition, straightway and the plane curved segment of abundance after water inlet, this just gives intake tunnel
Arrangement bring great difficulty, can not be solved using conventional layout pattern.Therefore, in view of Hydraulic and Hydro-Power Engineering generates electricity at present
The arrangement condition of diversion tunnel, research and inquirement are applied to the narrow and small new-generation diversion tunnel of topographic and geologic condition, layout area
Arrangement turned into design and scientific research personnel the problem of paying special attention to.
The content of the invention
The utility model provide a kind of intake tunnel layout pattern using vertical shaft transition, with solve by landform,
Narrow space caused by matter condition limits, the problem of diversion tunnel difficult arrangement.
The utility model adopts the technical scheme that：Water inlet section is connected with entering hole point, transition be located at water inlet section with
Enter the inner side of hole point junction, one end of upper flat section is connected by entering hole point with water inlet section, water inlet section axis and upper flat section
Axis is overlapped, and one end of lower flat section is connected with main building, and vertical shaft is set in the point of intersection of upper flat section axis and lower flat section axis, should
Vertical shaft upper end is connected with the other end of upper flat section, and the vertical shaft lower end is connected with the other end of lower flat section, the rotational angle theta of vertical shaft upper curved section
1 is 90 °, and the rotational angle theta 2 of vertical shaft lower horizontal section is 90 °.
The utility model has the advantages that：
（1）Very narrow and small suitable for layout area, the space for not having abundance after water inlet is arranged transition, straightway and put down
The intake tunnel arrangement of face curved segment.Diversion tunnel axle after intake tunnel water inlet axis direction is generally with water inlet
Line direction is inconsistent, and to ensure the positive water inlet of powerhouse of hydropower station, intake tunnel needs plane of arrangement curved segment.But by landform
The limitation of matter condition, water inlet and factory building relative position, water inlet Duan Houke layout areas are very narrow and small, do not filled after water inlet
Space arrangement transition, straightway and the plane curved segment of foot, you can using of the present utility model non-coplanar using vertical shaft connection
Intake tunnel layout pattern.
（2）Each position characteristics of compact layout of intake tunnel
By the way that the transition after water inlet is moved in water inlet section, merge water inlet section and transition, in water inlet section
Interior completion gradual change, the arrangement of non-coplanar upper and lower flat section is connected using vertical shaft, makes intake tunnel characteristics of compact layout,
Solve intake tunnel water inlet narrow space, difficult arrangement the problem of.
（3）Beneficial to the general layout of engineering
According to the limitation of the total arrangement of engineering and topographic and geologic condition, in the situation that water inlet and factory building position are selected
Under, after water inlet can layout area it is narrow and small, arrangement it is very difficult, according to routine diversion tunnel arrange, can not solve this lance
Shield.If readjusting the position of water inlet, factory building, generally require to carry out substantial amounts of survey and design work, spend substantial amounts of people
Power, material resources and time；Using arrangement of the present utility model, can vary without water inlet, factory building position premise
Under, solve above contradiction, beneficial to the general layout of engineering, make the general layout economical rationality of engineering.
The utility model structure is novel, safe and reliable to operation, easy for construction, very narrow and small suitable for layout area, water inlet
The space for not having abundance after mouthful arranges that the intake tunnel of transition and plane curved segment is arranged, and economical and practical, characteristics of compact layout,
Stability Analysis of Structures, diversion system arrangement it is straight it is smooth, have a wide range of application, there is good application prospect.
